Title: Low-density vinyl chloride polymer fibres and their production
IPC: C08J3/09
Filed: 1962-02-08
Abstract: A composition suitable for making microporous fibres of a vinyl chloride polymer of vinyl chloride content 85-100% having a density substantially below 1.4, contains as a porogenous component, dispersed in the solution, 2-25% (based on the weight of the polymer) of a water-soluble alcohol soluble to an extent above 2% (based on the weight of the polymer) in the solvent, chemically stable under the spinning conditions free from a tendency to leave the polymer with the solvent in a spinning operation, and incompatible with the polymer and insoluble in the solution of the polymer, and capable of being removed chemically unchanged from the fibres formed.  Thus, in dry spinning the porogenous substance should be less volatile than the spinning solvent, and in wet-spinning the porogenous substance should be insoluble in the coagulating bath.  The spinning solution may be made by first dissolving the porogenous substance in the spinning solvent, and then dissolving the polymer in the solution so obtained, causing separation of the porogenous substance as a fine uniform dispersion. The porogenous substance may be a mono-, di-, or polyhydric alcohol, e.g. allyl alcohol, isobutyl alcohol, ethylene glycol, polyethylene glycols, especially those with 1-5 ether linkages e.g. diethylene glycol, hexaethylene glycol, and trialcohols e.g. glycerol. Removal of the porogenous substance from the fibres may be effected by solvent extraction either in a special operation or in a finishing treatment.  The porogenous substance is water-soluble it may be extracted from the fibres with water or other aqueous liquid.  Specified dry spinning solvents include tetrahydro furan, ethylene oxide and propylene oxide, and a mixture of carbon disulphide, benzene or perchloroethylene with acetone.  Dimethyl formamide is specified as a wet-spinning solvent, to which isobutyl alcohol is added as the porogenous component, and the mixture is wet-spun into a mixture of dimethyl formamide and water. Filaments so made may be stretched by up to 5 times their original length in boiling water, and then shrunk if desired, also in boiling water. The density of the filaments obtained is from 0.9-1.35.

Filed: 1926-02-23
Abstract: 271,553. Kaye, F. Feb. 23, 1926. Fats and fatty oils, sulphuretted.-Emulsified palm or linseed oil or other oil or fat or mixtures thereof are treated with a vulcanizing agent whereby a gel is obtained, which, after addition of a coagulant, can be dried. The emulsified oil may be mixed with rubber or like latex prior to treatment with the vulcanizing and other agents. To oil &c. emulsified in a usual manner is added a sulphide or polysulphide such as that of ammonia, sodium, potassium, calcium, or barium, and after a time a gel forms. The addition of a coagulant such as aluminium sulphide produces a quicker drying of the gel. In examples (a) to 100 parts of linseed oil emulsified with alkali are added 10-30 parts of sodium sulphide and 2 parts of " Trimene " (the stearic acid salt of the condensation product of ethyl amine and formaldehyde), and the mixture is agitated until it darkens. This can be added to paper pulp with rosin size and alum, or spread on paper, fabrics &c. (b) To 25 cc. of latex containing 10 grm, of rubber is added 5 gms. of unboiled linseed oil, 5 gms. of sodium sulphide, and 1 gm. of sodium phosphate. The mixture is agitated for three days and can then be applied as above. The amount of vulcanizing agent may vary, but 0.5 per cent of the final product is suitable. Accelerators such as sodium or calcium phosphate may be employed.

Title: Conveyor installation with endless conveyor and means for the remote control of the distribution of work to work stations
Inventor: PAETZOLD GEORG
IPC: B65G47/48
Filed: 1960-02-17
Abstract: 890,873. Endless conveyers for delivering at desired positions. DURKOPPWERKE A.G. Feb. 17, 1960, No. 5562/60. Class 78 (1). In a conveyer installation provided with load carriers F continuously travelling in an endless path, each load carrier is provided with a selector W for the selection of stations St01- St38 which are to receive the load from the load carrier and there is provided at one point in the path of the carriers an ejection position MA having a contact device K for reading of the station characterizing number stored in the selector of each loaded carrier, this reading stepping on a step-by-step switch or counting mechanism associated with the selected station, the step-by-step mechanisms, upon registering more than a predetermined number of loads acceptable by each station, feeding an impulse to an ejection device provided at the ejection position MA, means being provided on one of the carriers to bring back the step-by-step mechanisms to their zero positions after each complete circuit of this carrier. The contact device K, Fig. 3 (not shown) comprises two parallel rows of switches 107, corresponding to the two rows of press-down keys in each selector W, and a main sensing member X which cooperates with a fixed contact member on the selector. The pressed-down keys of the selector of each carrier actuate the corresponding switches 107 which cause a current impulse to be fed to a step-by-step switching mechanism Z corresponding to the selected receiving station. When, for example, a carrier with its selector set for station St.25 engages the contact device K, switches X, 20 and 5, Fig. 2, are simultaneously closed causing a current impulse to be fed to a step-by-step switching mechanism Z25. When a predetermined number of pulses have been fed to mechanism Z25, it closes a circuit through contact 109 to an ejection mechanism AV comprising a delay relay 110 and electromagnet 111, the armature of which projects a roller into the path of a projection on the carrier, Fig. 4 (not shown), causing the carrier to release its load. Thereafter, since the contact 109 remains closed, all loads for station St.25 on following carriers are ejected at ejection plate MA. A switch pin on one of the carriers engages a fixed switch 117 to close the circuit for the return magnets 118, thereby bringing all the step-by-step mechanisms Z back to their zero positions after a complete circuit of the carriers. A control panel KP is provided with lights 105, to indicate vacant stations, and with a switch 123, Figs. 1, 2, in the circuit of the ejection device AV to eject the load from any carrier at MA, independently of the step-by-step mechanisms.
